J. Vernon McGee was in Bible College. When he met his first roommate he had quite a surprise. His roommate informed him that he had not committed a sin over the last three years. Dr. McGee was shocked to meet someone who was so sanctified in this life that he no longer slipped into sin.
As time went on, Vernon McGee’s roommate blamed him for everything that went wrong, no matter what. After the first semester, freshmen were able to change roommates. McGee went to his roommate and informed him that he was moving into another room with someone who was like him. That is, a sinner saved by grace who God was still doing a work in.
